Wire on Sea Strainer

[HotDirk01]

Subject boat is 36' SRV W/Onan Generator. Can someone suggest the purpose of the white wires shown in the pic of an aft sea strainer . Specifically do they serve to ground the Generator which is in close proximity?

Strainers are generally connected to the main bonding of the boat and I would have said that’s what you have. But bonding wires are supposed to be green for ID. Follow the wires back and see where they connect.

Would/could the generator be connected to the main bonding via the strainer?

Since these appear to not be part of the original wiring setup (although that's not out of the ordinary for a 40-year old boat), your only true means of figuring this out is to follow the wires as Brad mentioned. We'd only be guessing, which doesn't help. There appears to be a third wire, as well?

They do appear to be bonding wires. Someone must have changed them out to white. Odd but ok.

Everything that raw water running threw it or around it is bonded to a large plate under the boat. DO NOT PAINT that plate, the zinc, or under the piece of zinc.

What is causing my question is that a freeze broke the glass bowl in the strainer. Marina mechanic took the broken glass out for replacement, quit his job and left me to deal with it. Not a hard

fix and when I figure out how to get past the generator, I'll deal with it. However, now the generator won't fire and I was wondering if the wires (now disconnected) are the problem.
